Application filed April 23, 1915. Serial No. 23 ,307.-

To all whom it may concern: I V r Be it known that'I, Lours MEYERS, a citizen of the United States, residing at Brook lyn, in the county of Kings and State of New York, have invented certain new and: useful Improvements in Locks, of which the follow-' ing is a specification,

This invention relates to improvements in closures for doors, particularly sliding doors such as are-used in connection with elevators v in buildings. I

One of the objects of the invention is to providea closure'of the kindreferred to, comprising a fixed abutment, a rod having one end detachably' connected with the fixed abutment, and a member carried by the slid ing door havinga rotatable part which when turned to oneposition providesa passage through which the rod may be passed longitudinally, and which, when turned to another position, blockssuch movement of the rod; the said rotatable part being preferably key-and-manually operated.

Other objects and aims of the invention,

more or less broad than those stated above, together withthe advantages inherent, will be in partobvious and in part specificallyreferred 'to in the course of the following description of the elements, combinations, arrangements of parts, and applicatlons of principles constituting the invention; andthe scope of protection contemplated will appear from the claims. v

In the accompanying drawings, which are to be taken as a part of this specification, and in which I have shown one-ofth'e various possible embodiments of this invention as at present preferred: 7

Figure 1 is a perspective the application of my inventionto an ordinary form of elevator door; I r

Fig.2 isa front elevation, with parts in section and partsbroken away, illustrating the invention and its application; 1

Fig.3 is a sectional view, t aken on the line 3-3 of Fig. 2;

Fig. 4 is a sectional view, taken onthe line Hot Fig. 2; r

Fig. 5 is a detailview with parts in sec tion, illustrating the detachableconnec tion of the rod with the fixed abutment; I i Fig. Gisa plan view of a modified form of the pinion 30; and I 'Q 1 V Fig. 7 is asimilar view of a modified form of cylinder- '18 coeperating with such pin view, illustrating In the drawings, there is 'shown at 6 one of the doors controlling access: to an elevator shaft- This door may be pivoted in the usual .way, so that it can be swung out when necessary, although ordinarily it remains mthe positlon shown in Fig. 1. The

numeral 7 indicatesanother door, which'is slidablewith relation to the door 6, and the purpose of my invention, in the form illustratechis'to provide'means for holdingthe door; 7 inthe Fig; 1 position when desired,

and for permitting it to slide relatively to a the door 6 when necessary or desirable. I To this end, I may provide upon the edge of the door. 6, which, :by the way, in the present forin'of embodiment, is in a plane outs1de that of the door 7, a fixed abutment member which comprises a supporting plate 8 having a socket piece 9, 'provided-w1th a flared mouth 10, which socket member 9 is intended to receive one end of a locking rod 11. Preferably the socket member *9 is interiorly provided with a projection 12, which is intended to back into an 'annularxgroove 14=cut into the end of the rod 11. When the rod 11 has been inserted into thesocket member 9, it is held with its groove 14in engagementwith the projection 12,as1bv means of a presser 1 5 normally urgedto:

ward the rod by means of a coiled spring- 16' surrounding an operating rod 17 which pro'-' 7 7 trudes throughthe wall of thesocket mema her 9 as hown in Fig. 2. The other end of the 'rod 7 11 passes through a' cylinder :18

which-is rotatablyf supported in a casing '19, v

This casing 19 comprises a front plate 2 O,a rear plate 21, the latter being secured to the. door 7 and bothplates being interiorly' cut out to receive the cylinder 18, The cylinder has a stem 22 which projects throughfthe front plate and onthis stem there is a'knob 24 by which it may be-turne'd} The cylinder .has'a diametricalibore 25" adapted to snugly receivethe rod'll': It will be evident; that whenthe cylinder isturned to position-with.

its bOI'QfiII line with the rod 11, the rod-{1 1 maybe slid through it,-1and"when' the cylin p derl is in thejp'osition shown'jin Fig. 2,. slid?" ablemovement of the rod throu gh the cylin-f der is prevented; *Thecylinder has"on'fiitsf periphery a stop pin 26,;which makes con;

tact with suitablestops formed on thefiiiside of the'front plat-e 2l0,'so that the'turn'ing'f I I i movement 'ofthe cylinder is limited tea quarter ofa revolution."

V -.Preferably also there is a coiled 1 27 surrounding the stem 22 and bearing between the cylinder and the front plate 2-0, the

' said spring urging the cylinder toward the rear plate of the casing. The rear plat of the casing is provided with an aperture through which extends a squared shaft 28. The end of this shaft 28 within the casing carries a pinion 29 that meshes-with a pinion 80 secured to the rear face of the cylinder 18, so that rotation of the pinion 29 will cause rotation of the cylinder 18. The rotation of this squared shaft 29 is controlled as by means of a usual cylinder lock 32, which is properly positioned in the door 7, with its key-hole on the opposite side of the door from that occupied by the knob 24. A screw 31 may be employed to hold the pinion 29 upon the shaft 28.

It will be understood that the front and rear plates making up the casing 19 are cut out at the sides, as shown in Fig. 4, in line with the bore of the cylinder 18 when the cylinder is turned to a position in which the. axis of the bore will be parallel with the axis of therod 11. Consequently it will be evident, referring to Fig. 2, that if the cylinder 18 be turned either by means of the knob 24 or by the use of a key, so as to bring the bore of the cylinder in line with the axis of the rod 11, the door 7 may be slid back, the rod 11 simply sliding through the cylinder and the casing.

When it is desired to lock the door 7, the cylinder is turned either by means of the knob 24 or by the use of a key, to the position indicated in Fig. 2, so that the rod 11 cannot be moved lengthwise through the casing and the cylinder. If it is desired to remove the rod 11 entirely, the cylinder is turned so that the rod may slide relatively to the cylinder and the casing, and is pushed to the left (Figs. 1 and 2) sufficiently to clear the socket member 9, the presser 15 being of course raised so as to permit the rod to be lifted out of engagement with the projection 12.

The operation and use of this closure are believed to be almost selfevident from the description and disclosure, and need not be further referred to. It may be said, however, that so far as the application of the invention is concerned, it would make no difference whether the so-called fixed abutment, meaning the socket member 9, or its equivalent, were placed on the door 6 or on the door 7 or of course I might have but a single door slidable relatively to the door casing, and it would make no difference whether the door casing or the door, carried the fixed abutment, or which carried the locking cylinder.

In the form shown in Fig. 1, the knob 24 for controlling the cylinder, is supposed to.- be upon that side of the door 7 which faces into the room or apartment, while the cylindcr lock 32 is on the opposite side of the door, that is, upon that side of the door which faces the elevator shaft.

It will be evident that the device may readily be brought from unlocked to locked position from the inside of a room by pulling on the knob 24, resulting in the disengagement of the two pinions 29 and 30, whereupon the cylinder 18 may be turned to locking position, and then the knob 24 re leased and the spring 27 permitted to urge the'pinion- 30 back into engagement with the pinion 29. Instead of having the pinion 30 carried by or integral with the cylinder 18, I may provide a pinion 30, as shown in Fig. 6, pivoted to the back wall of the cas ing in fixed position, the said pinion being provided with a number of holes 33. The opposed face of the cylinder 18, as shown in Fig. 7, will be provided with studs 34 adapted to register with the holes Accordingly, when it is desiredto turn the cylinder from the inside ofa room, this is readily accomplished by pulling on the knob 24, whereupon the cylinder moves away from the pinion 30, after which the cylinder may be turned a quarter of a revolution and then allowed to spring back, when the studs 34 will again engage with the holes 33.

Inasmuch as many changes could be made in the above construction, and many apparently widely different embodiments of my invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.

It is also to be understood that the language used in the following claims is intended to cover all the generic and specific features of the invention herein described and all statements of the scope of the invention which, as a matter of language, might be said to fall therebetween.
